Of course ya can't blame the moon. !-)

I read sometime ago about research that posed the question about global warming affecting earthquakes. Something to do with making the crust less brittle, bit like (analogy warning) toffee. We are only talking about (average) 0.5 degrees, but then on what scale? Certainly Britain is rising in the north and sinking in the south due to rebound, as the ice that melted removed megatons off the higher latitudes and with rock it takes a long time. Rock is bendy on global scales, and more bendy as temperatures rise. Try bending a block of toffee and see the cracks appear, at certain temperatures.
Of course not all scientists agree about earthquakes being more numerous with global warming, but someone has done the stats and comes to that conclusion.
